The 1999 Ford Taurus utilises an adjustable headlight system which provides interim adjustment until the vehicle can be brought to a qualified service technician to verify the headlight alignment. This is a valuable feature in the event of a headlight failure where time or conditions may prevent you from visiting the dealer right away. After the initial adjustment, the vehicle should be brought to a certified adjuster at the earliest opportunity.
Park the vehicle on level ground with the gas tank half full. Remove any heavy items from the vehicle.
Open the bonnet and turn the headlamps on. Check the location of the bubble in the built-in headlamp level located at the top centre of the headlamp assembly. If the bubble is within four graduations of zero, leave the adjustments alone. If the bubble is not within four graduations of zero, the headlamp should be adjusted.
Adjust the headlamp by turning the vertical adjuster, which is located on the outside rear of the headlamp assembly, until the bubble is within the orange area of the gauge.
Adjust the left-to-right alignment by turning the horizontal adjuster, which is located on the inside rear of the headlamp assembly, until the angle gauge is at zero.
Take the car to a certified inspector to have the headlamp alignment verified at the earliest opportunity.
Maintain proper tire pressure as improperly inflated tires can affect the headlamp alignment adjustment.
Do not lean on the vehicle during this procedure. It must be level.
